GE Fanuc IC670ALG320 Field Control Analog Output Module
Configured for precise analog signal execution in Field Control systems, the GE Fanuc IC670ALG320 (IC670ALG320 Analog Module) provides direct physical signal processing across 4 isolated output channels. It converts digital words from the Bus Interface Unit backplane into proportional 0-20 mA, 4-20 mA, 0-10 VDC, or 0-12.5 VDC control signals to drive field actuators and valves.

Backplane Bus Communication Velocity & I/O Density Scaling
The IC670ALG320 maintains backplane bus communication velocity across local expansion racks while providing high I/O density scaling in control enclosures. Integrated optical isolation barriers protect internal logic circuits against ground loops and field transients, ensuring deterministic output updates without corrupting system scan cycles. Firmware flash compatibility across parent CPU units guarantees stable backplane handshake operations during continuous 12-bit digital-to-analog conversions.
Frequently Asked Questions
Q: What are the external power supply requirements for the IC670ALG320 module?
A: The module requires an external power supply of 20 VDC to 29 VDC with a maximum ripple of 5%, consuming up to 180 mA during active operation.
Q: How does the IC670ALG320 isolate field signals from local backplane logic?
A: Optical isolation barriers provide galvanic isolation rated at 250 VAC continuous and 1500 VAC for 1 minute between field outputs, logic circuits, and frame ground.
Q: What current draw does the IC670ALG320 place on the local Bus Interface Unit?
A: The module draws a maximum of 51 mA directly from the 5 VDC internal logic supply of the Bus Interface Unit backplane.
Field Installation Guidelines
- De-energize primary backplane power and external 24 VDC field power before inserting or removing the module from its terminal base.
- Secure field cabling to the removable terminal block using shielded twisted-pair wires to suppress noise on analog loops.
- Connect cable shielding to panel earth ground at one end only to prevent ground loop currents across isolated output circuits.
- Verify channel output mode selection prior to applying external power to connected actuators or positioning valves.
- Maintain adequate enclosure ventilation to prevent ambient operating temperatures from exceeding +60 deg C.
